What is spectroscopy?
Spectroscopy is a scientific method for analyzing materials that involves studying how light or other electromagnetic waves interact with substances. By measuring the absorbed or emitted radiation, conclusions can be drawn about a material’s chemical composition and structure.
This technique is used in many fields, such as chemistry, physics, and materials research, to identify substances and determine their properties. Spectroscopy is frequently used in quality assurance, environmental analysis, and pharmaceutical research.

Applications for Spectroscopy
Plastics industry
In plastics analysis, spectroscopy enables the rapid and precise characterization of materials. Raman and FTIR spectroscopy provide unique spectra that reflect specific molecular vibrations. Using these techniques, we can identify plastics, fibers, and particles as small as 1 µm, detect contaminants, and quantitatively determine known substances. With these methods, we provide you with reliable support for material analysis and quality assurance.
Automotive
In the automotive industry, spectroscopy plays a central role in quality assurance, particularly in the detection of filmic contaminants and particle analysis. It is used to precisely examine components such as transmissions, powertrains, internal combustion and electric motors, and fuel cells. Using these methods, we enable a detailed analysis of surfaces and materials and make a decisive contribution to ensuring the reliability and longevity of your vehicles.
Medical Technology
Identifying contaminants and characterizing materials: In medical technology, mapping measurements combined with Raman and FTIR spectroscopy are an important tool for analyzing implants, stents, and products used in dialysis, transfusion, infusion, and injection. They enable the precise identification of particulate contaminants as well as the characterization of plastics, coatings, and residues. When combined with other methods, the causes of contamination can be quickly determined—an important foundation for quality assurance and product safety.
Environmental Analysis
In environmental analysis, spectroscopy is an important tool for monitoring and assessing environmental pollution, for example, for identifying and quantifying pollutants in air, water, and soil. Using techniques such as UV-Vis, IR, and Raman spectroscopy, we can specifically detect contaminants such as heavy metals, organic pollutants, and toxic compounds.
Packaging Analysis
Determining material compositions, ensuring quality, and meeting regulatory requirements: In packaging analysis, spectroscopy is a key tool for identifying plastics, additives, and coatings. It enables reliable testing of material properties, detection of contaminants, and targeted analysis of critical substance groups such as PFAS and PAHs. Furthermore, it supports the investigation of migration potential between packaging and contents. By utilizing modern spectroscopic methods, manufacturers can efficiently ensure the safety and compliance of their packaging while simultaneously optimizing their quality standards.
Frequently askes Questions about Spectroscopy
Spectroscopy is a scientific method for analyzing materials that involves studying how light or other electromagnetic waves interact with substances. By measuring the absorbed or emitted radiation, conclusions can be drawn about a material’s chemical composition and structure.
This technique is used in many fields, such as chemistry, physics, and materials research, to identify substances and determine their properties. Spectroscopy is frequently used in quality assurance, environmental analysis, and pharmaceutical research.
Spectroscopy enables the analysis of a wide variety of samples in different states. This includes solids such as plastics, metals, and pharmaceutical tablets, to determine their chemical composition and structure. Liquids such as water samples, oils, and chemical substances can be examined for their molecular structure and concentrations. Gases and ultrafine materials such as powders and microplastics can also be analyzed using spectroscopic methods to determine their composition and impurities. This versatility makes spectroscopy a valuable tool in materials analysis and quality control.
There are a wide variety of spectroscopic techniques. The basic distinction is between atomic (e.g., X-ray spectroscopy), molecular (e.g., microwave spectroscopy, fluorescence spectroscopy), solid-state, impedance, and laser spectroscopy.
FTIR and Raman spectroscopy, like UV/VIS spectroscopy, fall under the category of molecular spectroscopy. Energy-dispersive X-ray spectroscopy (EDX analysis) and optical emission spectrometry (OES) are classified as atomic spectroscopy.
While some of these methods are ideally suited for specific analytical tasks or certain classes of substances, others are virtually universal in their application.
In modern chemistry, spectroscopic methods are not always used in isolation. For example, FTIR spectroscopy can be combined with thermogravimetry (TGA) to identify and quantify decomposition products released during plastic analysis.
In correlative particle analysis, SEM-EDX analysis as well as FTIR and RAMAN spectroscopy can be combined with optical microscopy to identify and classify inorganic and organic particles.
